CONDUIT' FITTING Filed May 24, 1926 IN V N TOR 6c 5d ATTORNEYS Patented Sept. 8, 1931 UNITED STATES PATENT FFNIE HOWARD A. SELAI-I, OF ERIE, PENNSYLVANIA, ASSIGN 01% TO MALLEABLE IRON COMPANY, OF ERIE, PENNSYLVANIA, A CORPORATION 033 PENNSYLVANIA CONDUIT FITTING Application filed May 24, 1926. Serial No. 111,250.

This invention is designed to improve conduit fittings, and particularly such fittings where it is desired to carry the wires to a single fixture and particularly where the fixture is supported directly by the fitting. One of the principal objects of the invention relates to so shaping the fitting as to add to the ease with which the wires may be passed into and out of the fitting. Features and details of the invention will appear more fully from the specification and claim.

The invention is illustrated in the accompanying drawings as follows Fig. 1 shows an elevation of a conduit sy tem.

Fig. 2 a central section through one of the fittings.

Fig. 3 a plan view.

Fig. 4 an enlarged View of the fitting slightly differing in structure from that shown in Fig. 2.

1 marks the body of the fitting. This has the extensions 2 at each end, these extensions being provided with conduit openings. Internal screw threads 3 are arranged in the extensions and a surrounding engaging sur face 4 is provided at the outer ends of the extension.

Clamping sleeves 5 are made collapsible by means of slot 5a and they have the screw threads 6 engaging the screw threads 3, the tapered intermediate portion '1' engaging the surfaces 4 and a wrench-hold portion 8 by means of which the sleeve may be turned into place so as to engage and clamp an inserted conduit, or fitting 9. These are arranged at each end of the fitting.

A side opening 10 is provided with external screw threads 11 adapted to receive a fixture, such as a clamp C. The passage 12 of the side opening communicates with the passages 13 which extend from the conduit openings.

he passages 13 are deflected toward the passage 12 by the deflecting projection 14 ex tending from the wall of the fitting opposite the side passage 12. Guard shoulders 2a are provided at the inner ends of the extension so that the ends of the fitting are guarded. A conductor wire A if fed into the opening at the end of the fitting is deflected by the defiector 14 into the passage 13 and out into the conduit. This slmphiies the leading in of the wlres very much in this type of structure.

Further th e structure gives such rigidity that to a very la e extent the conduit itself may be used as tures.

tlcuiarq such art wire is ca a fran'le-worh for carrying the fix- It will be understood that this is parpplicable to lighting fixtures and es worxing in series in which the ed into and out of the operating nxtures, such as a iighting fixture as shown.

oxes are used involving covers and it Wlll be understood that the side opening may be provided with a 1 v. 1 H tnieaciess nanner as coup ing ano fitting in the same the ends and at least one of the bodies is has its side opening so arranged.

The body of the fitting is provided with a web 15 in the gore formed between the bends leading to perforated if desired. these feet the side openin and this has a foot 16 by which it may be secured.

It will be noted that by placing on the web in the gore clearance may be obtained for the insertion of the screw while the feet extend laterally only to the extent of the thickness of the fitting itself.

Thus a ver y compact structure is provided.

In the construction shown in Fig. 4c the side opening has the internal screw threads as distinguished iroin the external threads and is adapted lamp D.

to receive a fixture in the form of a The fixture is also provided with the screw-threaded lugs 17 into which screws 18 are passed for securing a shame or fixture n at right angles to the web having screwreceiving openings. the major portion of the feet being within the cross dimension of the body of the fitting.

In testimony whereof I have hereunto set my hand.
